Decomposition Characteristics of Ethane Hydrate and Propane Hydrate by Microwave Heating [PDF]
Acta Physico-Chimica Sinica, 2010 The decomposition of type I ethane hydrate and type II propane hydrate stimulated by 2.45 GHz microwave (MW) were experimentally investigated. The decomposition characteristics of the hydrates under MW heating were analyzed based on the two. step dissociation mechanism accompanied by heat and mass transfer at the crystal surface.

Advanced Functional Materials, EarlyView.Controlling counterion exchange rate during aqueous phase separation enables the formation of skin‐free, homogeneously porous polyelectrolyte complex hydrogels by suppressing kinetically trapped skin layers and macrovoids. The resulting hydrogel networks exhibit exceptional toughness (∼15 MJ·m−3) and enable 3D (bio)printing and post‐functionalization ...

Electrostatic Superlattices Beyond 1:1 Stoichiometry
Advanced Functional Materials, EarlyView.Polymer‐mediated charge regulation drives two hierarchical routes to higher‐stoichiometry nanoparticle superlattices. Tuning the polymer's molecular weight promotes progressive interstitial filling, transforming ZnS into the fully occupied CaF2${\rm CaF}_2$ lattice. Exchanging polymer assignment between large and small nanoparticles instead breaks CsCl
